Abstract
The pedagogic element in Berton Coffin's work was the "favorable vowel chart," later published in color as the "chromatic vowel chart for voice building and tone placing." Based on the then accepted linear source-filter theory of vowels, the chart shows which vowels most likely resonate the fundamental frequency and harmonics of any note in the vocal range. The main difference between the current nonlinear source-filter interaction theory and Coffin's linear theory is that formants need to be avoided, not sought out, in the choice of a vowel. It is still true that formants can boost the energy of any harmonic of the source, but this selective "boosting" often creates irregularity in the vibration pattern of the vocal folds. In practice, the new theory is less restrictive because harmonics and formants do not need to be fine-tuned to each other.
